Fluid

Cannot see the menu in Fluid2 ?

In Fluid2 the menu does not appear automatically: You can bring it up by pressing FIVE FINGERS simultaneously on the screen :) !

iPad "Change background" bug

I've received numerous emails from users mentioning they cannot select a picture from an album since they updated to iOS 4.3.1. It seems the last update broke this feature, but I have fixed this issue now and submitted a new build to Apple, hopefully it will be approved soon.

iOS 4 crash :( !

I've received numerous emails mentioning Fluid and Fluid2 crash on second launch after updating to iOS 4. I've worked around the clock to generate a patch and it is now sent to Apple. I've also contacted the hotline so it will be considered an emergency fix. I keep my finger crossed it won't take too long to get to you guys.

Is "Fluid" too fast ?!

A few person emailed me since the released of "Fluid v1.3". It seems that it is running too fast now. The reason this issue was undetected is that I am doing all my testing on my personnal iPhone (First generation). Fluid v1.3 is using the optimized engine of "Fluid 2" but I did not notice the change until I saw the application running on my friend's 3GS.The solution

I'm getting a 3GS from the Apple Store this afternoon, I will release a fix tonight: "Fluid v1.4" and "Fluid 2.1". The speed will be constant with ability to control it further via a slider. I hope Apple won't take forever to released them.

1,000,000 downloads...version 1.2 coming !

Never I would have expected so many downloads. I've received numerous positive review for the version 1.1 of Fluid.
I'm working hard on fixing every bug reported, I just sent the version 1.2 to Apple:

Background modification now works for any picture of any format.

Music is no longer mandatory, iPod music will keep playing if you turn Fluid's music off.

Music button never gets out of sync.

Next week, I will keep fixing bug in order to release a version 1.3...and also "Fluid Premium". Stay tuned.

700,000 downloads...and counting !

Not bad for what was supposed to be just a "demo" during my job hunting process.
A lot of people have asked for a music and ability to change the background. Version 1.1 is currently being reviewed by Apple and will allow this:

And that's it! Set an initial height perturbation in the last state, iterate at 30fps: Voila des vagues !

Rendition

From the heigthmap, we then generate a mesh. Assuming that every pixel ray come to the mesh at (0,0,-1), we can generate a perturbated View Vector. We use these pertubated vectors to offest the textures coordinates.

Performance

Right now, only reflection and refraction are simulated via a bottom texture and an environment map texture. The rendition requires two passes.
I tried to add the caustics but without multi texturing, this would have requiered a third pass, unafforable for now.
